It's been said that when you're searching for a brilliant idea you should write down every single idea you get, no matter how foolish they seem to be. One of the silliest may become the golden one with just some fine tuning. But if you ditch it right when it pops into your mind, it may be lost forever. For me there's a couple favourites in your sketches, a couple of too obvious ones and a couple that look forced. And there's one that inspired me to create yet another H, and yet another, just to visualize the ideas.
Many of your H's seem to have an oriental twist, reminiscent to the Yin-Yang symbol. Is that coincidental or does it reflect your state of mind? Based on the balanced quality of your works I'd vote for the latter...
